A higher frame rate provides smoother motion for videos. Lower frame rates will result in stuttering

motion. The maximum number of frames that is displayed in 1 second. 30 fps is the highest video

quality for this camera. In general, any frame rate above 15 fps is imperceptible to the human eye.

This limits the maximal refresh frame rate, which can be combined with the "Fixed quality" option to

optimize the bandwidth utilization and video quality. If xed bandwidth utilization is desired regardless

of the video quality, choose "Constant bit rate" and select the desired bandwidth.

The bps will affect the bit rate of the video recorded by the camera. Higher bit rates result in higher

video quality.

Select the image quality level for the camera to try to maintain. High quality levels will result in

increased bit rates.
